This is my simple fan holder to cool the ramp or other controller board.
And it just sit on and clamped into the side frames. use a double adhesive tape also will work
easy t adjust the position by sliding it upward or downward
Fan i use is ROUND FAN with 9,5cm diameter. BUT any other fan is can be used
